I'm just sad I literally missed the chance to sign up by an hour or so! They'd just posted this the day I decided to finally sign up.
A few others have done the same thing, I've noticed. I've taken it as a lesson to sign up even if I don't plan to use it right away.
It's really great that more people are getting into crypto, though. Not just in a mainstream Bitcoin way, but with the altcoins as well.
